WILLIAM A. EISENHOWER, OF FRIEDENSBURG, PENNSYLVANIA Letters Patent No.102,667, dated May 3, 1870; anterlatefl April 29, 1870.

IMPROVE!) SASH-HOLDER.

The Schedule referred to in these Letters Patent and making -part of thesame.

To all whom it may concern:

Be it known that I, XVILLIAM A. ErsnNHoWnn, of Friedensburg, county oi'Berks, State of' Pennsylvania, have invented an Improved Retaining andLocking Device for 'Window-Sashes; and I do hereby declare the followingto be a full, clear and exact description of the same.

My invention consists in the combination of an elastic roiier, a yokesliding in a sash, provided with a handle, having a square shoulder andpressed outward by a spring, and a recess in the frame into which theyoke and roller pass when the sash is down, all as fully describedhereafter', so that, while the pressure of the elastic roller retainsthe sash in any position 15o-which it is adjusted., the yoke passinginto the said recess, when the sash is down, will lock it so that itcannot be raised until the yoke is retracted by means of its handle.

In order to enable others to make and apply my invention, I will nowproceed to describe its construction and operation, reference being hadto the accompanying drawing, which forms a part of this specification,and in which- Figure 1 is a portion of a window-frame and sash, with myimproved retaining and locking device.

' Figure 2 the same, showing the sash lowered to the bottom of thewindow-frame, and

Figure 3 a sectional plan view on the liuc 1 2, fig. 2.

A represents part of the window-frame, and

B part of a sash, arranged to Slide in the frame in the usual manner.

A portion of the side and edge of the sash is cnt away for the receptionof a metal case, C, in which is arranged to slide a rod, a-fthis rodpassing through a partition, b, of the case, and being bent at right angles at its rear end, so that it may project through a slot, e, formedin the said case, and thus be operated from outside the latter.

To the opposite end of the rod a is secured a bent metal-plate or yoke,.I, whichis arranged to fit snugly and slidefreely within the case C.

A spiral spring, k, which bears against the partition b and yoke, has atendency'toforce the latter outward from the case and toward theadjacent edge of the window-frame.

A roller, H, of gum-elastic or other equivalent material, is arranged toturn on a spindle in the yoke F, and is arranged to bear against theedge x ofthe window-frame, excepting when the sash is lowered to itsfull extent; it then, together with a portion of the yoke, entering therecess j formed in the said Windowframe. c

It will be observed, on reference to fig. l, that when l the sash ispartially raised the yoke is contained entirely within the case C, whilethe roller H bears against the edge x of the window-frame, and the rearend of the rod a against the back of the case.

By means oi' this arrangement sufficient friction is created to maintainthe sash in any position to which it may be adjnsted,vwhile, as thespring h is not intended to aid in thus forcing the friction-rolleragainst the edge of the window-frame, it may be compara tively weak, theonly duty of said spring being to shoot the yoke or holt L'u into therecess j, in order to lock the sash and prevent it from being openedfrom the outside when lowered to its full extent.

It Will be seen that, when the yoke has thus entered the recess j, aportion of it is still contained within the case G/and is sc firmly heldbythe latter that it forms a most rigid and effective bolt for theretention of the sash.

The projecting end of the rod a aiiords a ready means of withdrawing theyoke and its roller from the recess j when the sash is to be raised.

It will be evident that the device can be as readily applied to thelower as to the upper sash ot a window'.

I am aware that spring-bolts adapted to recesses in the frame have beenused for locking sashes, and that elastic rollers for retaining thesashes in positions to which they are adjusted have been employed, bothalone and in combination with locking devices.

I am also aware that spring-rollers have been used in connnection withnotched side frames, but none of these devices are of such a characteras to retain the sash in any position to which it is adjusted, and alsolock it when down so that it ,cannot be raised by merely applying upwardpressure to the. sash.

C Zalm'.

The combination of the elastic roller H, its yoke F, sliding in thesash, and adapted to a square recess, j, in the sash-frame, the handle aconnected to the yoke, and by which the latter can be withdrawn fromthe-recess, and the spring 71;, by which the yoke is forced into therecess, the whole being so constructed and arranged that when the yokeand roller are in the said handle, and the sash is so securely fastenedthat it cannot be raised by the mere application of an upward pressure.

I n testimony whereof I have signed my name to this specification in thepresence or" twosubscribing Witnesses. WM. A.'EISENHOWER. Witnesses:

said recess they can only be withdrawn by operating
